The automatic rolls when players have no move(s) are a time-saving feature.
The pseudorandom rolls that should appear occur far less seldom than expected, particularly when one player is far ahead of the other. In those situations the app rolls combinations that only increase the gap. Ive noticed that exiting the app then returning at a later time levels the inequity, or at times even flips it.
